bookChallenge: Build a Mini Library System

Recap: OOP Concepts for a Library System

As you reach this stage, you have explored the essential building blocks of object-oriented programming in PHP. You have seen how classes can represent entities such as Book, Member, and Library, and how properties and methods allow you to store and manipulate data within these entities. Through inheritance, you can share behaviors and attributes among related classes, creating a more organized and efficient codebase. Finally, you have learned how exception handling enables your programs to manage errors gracefully, ensuring robust and predictable behavior.

You are now ready to combine these concepts to implement a mini library system that models real-world interactions between books, library members, and the library itself. This challenge will test your ability to design classes, work with object properties and methods, apply inheritance where appropriate, and handle error conditions using exceptions.

Opgave

Swipe to start coding

Implement a mini library system using object-oriented programming concepts. You will create classes for Book, Member, and Library, each with appropriate properties and methods. Your implementation should allow members to borrow and return books, and handle error cases using exceptions.

  • Define a Book class with properties for the title, author, and borrowed status, and methods to borrow or return the book. Throw an exception if a book is borrowed twice or returned when not borrowed.
  • Define a Member class with a name and a list of borrowed books. Include methods to borrow and return books, and throw an exception if a member returns a book they have not borrowed.
  • Define a Library class that manages collections of books and members. Include methods to add books and members, and to let members borrow or return books by name and title. Throw exceptions if a book or member is not found.
  • Ensure exception handling is used to manage error situations.
